Three common compounds used in "ice melt" are magnesium chloride, calcium chloride and sodium chloride. At 20EC, 37.45 g of CaCl2 was soluble in 50.O mL of water, 135.75 g of MgC12 was soluble in 250.0 mL of water and 360 g of NaCl was soluble in 1000 g of water. a. What is the solubility of each? Which is the most soluble at 20 deg. C? b. For the two alkali earth compounds, was hydration energy or lattice energy responsible for the solubility trend? For the compound that is the MOST soluble, what is the: c. Freezing point and boiling point
